Judges 7:4-6

GOD said to Gideon: “There are still too many. Take them down to the stream and I’ll make a final cut. When I say, ‘This one goes with you,’ he’ll go. When I say, ‘This one doesn’t go,’ he won’t go.” So Gideon took the troops down to the stream. GOD said to Gideon: “Everyone who laps with his tongue, the way a dog laps, set on one side. And everyone who kneels to drink, drinking with his face to the water, set to the other side.” Three hundred lapped with their tongues from their cupped hands. All the rest knelt to drink.
